Objective To compare the differences in behavior characteristics among SHR, WKY and SD rat models of attention deficit/hyperactivity disorder (ADHD), and explore an ideal control model of SHR rats.Methods Using open field test to analyze the rat movement distance, speed, wearing numbers and the number of grooming to evaluate the spontaneous movement in SHR, WKY and SD rats.Using the Morris water maze to test the learning and memory ability among the three rat groups.Results The result of open field test showed that the SHR rats had significantly increased (P< 0.01) total amount of exercise, average speed and wearing numbers than WKY and SD rats.Compared with the WKY rats, SD rats had a significantly higher movement distance (P< 0.01), slightly higher movement speed and wearing number (P< 0.05).In the Morris water maze hidden platform period test, the SD rats had a significantly longer latency than the SHR rats (P< 0.05).SD rats showed longer latency distance on the first, third and fourth days of training, as compared with the SHR rats (P< 0.05 or P< 0.01).Compared with the WKY group, SD rats showed a shorter latency distance in each training time (P< 0.05 or P< 0.01).In the probe trial period, the SD rats showed shorter time and distance ratio to the target quadrant than SHR rats (P< 0.05), while significantly longer than the WKY rats (P< 0.05 or P< 0.01).Conclusions There are significant behavioral differences between SHR and WKY rats, showing certain disadvantages in comparison of the two types of rats.To add SD rats as a control group for SHR rats can improve the comparability of behavior characteristics of SHR rats, and to get more objective evaluation of the behavior characteristics of SHR rats.

Objective To understand the status of stroke patients' perceived control and healthrelated quality of life,and to analyze the effect of perceived control on stroke patients' depression and health-related quality of life.Methods By convenience sampling,264 stroke patients were chosen to complete the questionnaire survey,Perceived Control Questionnaire,Hamilton Depression Scale and ShortForm Health Survey Scale-2.Results The score of patient's perceived control and health-related quality of life were (18.21±2.74),(46.62±11.56) points respectively.The perceived control had a negative correlation with the depression (r=-0.32,P ＜ 0.05),had a weak positive correlation with the body health (r=0.05,P ＜0.05),and had a positive correlation with the mental health of health-related quality of life (r=0.29,P ＜0.05),depression was negatively correlated with health-related quality of life of the body health,mental health (r=-0.26,-0.28,P ＜ 0.05).Conclusions Medical personal should improve the level of stroke patients' perceived control through various methods,to reduce depression and improve health related quality of life.

BACKGROUND:Zirconia is considered to be one ofthe promising prosthodontics materials because of its high strength, high hardness, excelent wear resistance and excelent corrosion resistance. However, the development of zirconia is hindered owing to the uncertainty in long-term stability of zirconiaal-ceramic crowns such as the cracking (chipping) of veneering porcelain and deterioration of mechanical properties of zirconia dental crowns under intraoral conditions.
OBJECTIVE:To summarize the preparation of zirconia bioceramic and its application progress in the field of prosthodontics.
METHODS:The properties, crystal structure, preparation and use of zirconia in prosthodontics were reviewed. Reasons that affected the stability of zirconia were also discussed. The future development of zirconia was forecasted.
RESULTS AND CONCLUSION:Preparation of zirconia bioceramics involves the folowing aspects:powder synthesis, biscuit molding, and ceramic sintering.To improvethe istability of zirconia al-ceramic crowns,we optimize the preparation of zirconia powder topromotethe purity, mechanical properties, biological properties and stability. Furthermore, it is necessary to explore the effects of crystal nucleation, growth, second phase and grain size on crystal stability and biomechanical propertiesof thetooth abutment, as wel astoconduct an in-depth theoretical analysis on the effect oftooth abutmentand lattice matching of porcelain crowns on the interface.

Autoimmune encephalitis is a kind of inflammatory disease of central nervous system caused by abnormal immune response of body immune system to neuronal antigen,and is generally considered to be reversible encephalitis caused by noninfectious factors.Its characteristic manifestations include acute and subacute onset of cognitive dysfunction,epilepsy and mental disorder.With the discovery of related antibodies,summaries of clinical syndrome and application of new functional imaging instruments,the diagnosis of autoimmune encephalitis is increasingly standardized.The priority treatment of autoimmune encephalitis is immunomodulatory therapy,including glucocorticoid,immunoglobulin,plasma exchange and immunosuppressant.The other treatments could be the related tumor resection,electroshock therapy,etc.The symptoms in most patients can get substantial relief with active treatment.The present paper would focus on the research progress in treatment of autoimmune encephalitis.
